The deposit type wheels will normally remain in their zero positions, but this invention includes mechanism which will move the deposit type wheel one space in order to bring type to the printing line which will print an identification, as T Dr.. The same thing is true when the total lever is moved to the Withdrawal position. The mechanism will then be operated to move the withdrawal rack and bring the type wheels from their zero positions to position to print an identification, as T CL. The mechanism for accomplishing this result will now be described in detail.

Withdrawal and deposit banks.

In Fig. 1 the withdrawal bank is shown.

It is provided with nine keys 30, mounted in a key frame 31, supported on the rods 32 and I 33 in the usual manner. Each of'the keys has a shoulder 34, adapted to cooperate with a pin 35, carried by a detent bar 36, supported by pivoted links 37 and 38 pivoted to the key frame. When a key is depressed, the shoulder 34 passes beneath the pin and is thereby held in its depressed position. The link 38, which supports the lower end of the detent bar 36, is extended to form a hook 39, adapted to cooperate with a pin 40, carried by a zero stop pawl41, supported by a short shaft 42, in the key frame.

'VVhen any key in the withdrawal bank is depressed, the zero stop pawl 41 for this bank is rocked to its ineffective position. If no key is depressed, the zero stop pawl is adapted to disconnect the latch of the appropriate differential mechanism in a man-' ner well known in the art, and described hereinafter.

1 The differential mechanism appropriate to the withdrawal bank is a duplicate of that for the deposit bank, and therefore, the description of one will be suflicie'nt for both.

Thedifferential' mechanism includes a differentially movable member 45, which carries a link 46 and a bell crank lever 47, pivoted thereto. -T his link and lever in turn pivotally support a latch 48, which cooperates with a shoulder formed on adrivingsegment 49, loosely mounted on a Stud 50. The driying segment is rotated first clockwise and then counter-clockwise during each opera tion of the machine. This movement is given to the driving segment by means ofa' pairof cams 50, which together actuate a Y shaped lever 51, well known in machines of this type.

carricsthe type wheels 72 and 73.

crank lever 47 contacts with whichever one of the keys in its appropriate bank has been depressed, and thereupon causes the latch 48 to be disconnected from the shoulder of the driving segment 49, which continues its clockwise movement. If no key in a bank is depressed, the latch is disconnected by the contact of the outer end of an arm 53 with the zero stop pawl 41. The arm 53 is journaled at its inner end on the stud and at its outer end,..is connected tothe forward end of the bell crank lever 47 by a slot-and-pin con- I nection, as is well known.

livotcd to the differentially movable member 45 is a beam 55. This beam 55 is bifurcated at its right-hand end, and cooperates with a pin 56 carried by a link 57. At its upper end, the link 57 is connected to a segment 58. the purpose of which is well known and will not be described herein. lower end, the link 57 is pivoted to an arm 59, secured to a spiral segment 60, loose on a rod 61, supported by the machine side frame. Segment 60 meshes with a spiral gear 62, fast on the shaft 63, which is supported by the printer frames 64 and 65. At its for ward end, the shaft 63 carries a segment 66, (Figs. 1 and 5), which meshes with teeth At its formed on the lower edge of a rack 67 extend- Pointing mechanism.

On its upper edge, the rack 67 carries teeth 69, adapted to mesh with a pinion 70, supported on a shaft This pinion is connected by a tube to another pinion '71 (Figs. 5 and 7) which meshes with two type wheels 72 and 73, loose on rods-74 and 75. It can be seen that the differential movement of the differentially movable member 45 is transmitted through the beam 55, link 57, spiral gear 60, spiral gear 62, shaft 63, segment 66, to the rack 67, which, in turn, operates the pinions 70 and 71. and causes both of the type wheels .72 and 73110 rotate to a position correspondwithdrawal and the deposit. banks.

Fig. 4 shows one of the type lines which This figure is a top plan view of the upper type wheels 72. There are four groups of amount type wheels 78, two type wheels 72 appropriate to the withdrawal and deposit banks,

and six type wheels 79 appropriate to the ledger number keys, whieh are not shown and described in this application.

It will be noted that the type wheels 72,

which are shown in their normal positions, do not carry type at the printing line. In the position below the blank position, however, it can be seen that the types TD and TC appear, these letters standing for Total debit and Total credit.

it can be seen from Fig. 3 that should the I total lever 123 (Fig. 2) be moved downward in the slot to the second position below its adding position, which position is appropriatev to the deposit bank, and should no key in the deposit bank be depressed when the machine is operated to take a total, the totalizer which is appropriate to the Zero position of the deposit bank will be selected. This totalizer is for the purpose of accumulating the total withdrawals or debits. When this operation occurs, it is desired to print TD tor 'llotal debit on the record receiving medium, but as thezero position of the rack 67 is a blank position, it is necessary on this operation to move the rack one position to the left. This movement oi the rack or to the left will set up the total debit type at the printing line, in order that this designation oy be printed with the total from the Total hebit totaiiser.

The mechanism for accomplishing this one-step movement oi the rack 6'? on this operation, will now be described:

The invention utilizes mechanism which been known in machines of this type as ination mechanism, in order to he :iunction above pointed out. lied that the zero elimination eohanisni r the nirpose oi? moving the cks associated with ai'i'iount type wheels aliens than that on which significant digit of the t up on the type wheels in zeros of the amount type tally in the zero bring a blank position of i -the printing line-i Each of k appropriate tothe withdeposit banks, has a projeci'n rand end, adapted to cooperate with a st ylder 91, formed on a coupling member 92, pivoted to one arm of a boil crank lever 94, loose on a shaft 95., supported by the printer iraine.

it link comm-ts the remaining arm of the bell crank lever S t. with a bell crank lever 96. loose on a rod 07. The bell crank lever carries two rollers 98 and 99 which cooperate with a pair of cams 100 and 101, fastened on a shaft 102, which is the main drive shaft of the printing mechanism. This shat't receives one rotation in a counter-clockwise direction at every operation of the machine. The formation of the cams 100 and 101 is such that the bell crank lever 96 will be rocked irst clockwise from and then counter-clockwise to its normal position. The clockwise movement of the bell crank lever 96, will, through the link 95, rock the bell crank lever 94 clockwise and then counter-clockwise.

The rack 67 is normally held against movement toward theleft, due to a spring-pulled lever 10%, loose on a shaft 105 and having a nose cooperating with a downwardly extending projection 106 on the rack. It is apparent from Fig. 5 that if the coupling member 92 is in the position shown in this figure, the clockwise movement of the bell crank lever 9-l will have no effect on the rack. lVhen printing a total of all deposit items, or of all withdrawals, it is desired to move the rack to the left in order to bring the appropriate designating type to the printing line, to which end, means is provided for lowering the coupling member 92 until the shoulder 91 thereon cooperates with the projection 90 on the rack. The coupling member 92 is normally held in its-elevated position by means oi? an arm 10S, loose on a rod 109, and

having a projection 110 extending from its lower edge and resting on appropriate cam disc 111.

Disks 111 fast with each other, turn on a suitable support and are positioned by the total lever 123 in a manner which will be hereinafter described. There is one of these disks appropriate to the deposit bank, and another appropriate to the withdrawal bank. The disk 111, shown in full lines in Figs. 5 and 6, is the one for the withdrawal bank, and partial." hides the disk asso 'iated with the deposit bank, These disks are formed withhigh and low portions on their upper edges. The disk for the withdrawal bank is so formed that the arm 108 which rests thereon, will not be lowered until he total lever 123 moved to one of its extreme upper or lower posi ions, The disk appropriate to the deposit onic, however, is cut away so that the arm appropriate thereto will be lowered when the total lever is moved to either the second position above or the second position below its adding position. Should the total lov moved to its first position above or be" its adding position, the

ow disks both have high portions in those positions, thereby preventing either of the arms 108 from being lowered. When the disks 111 are moved to the position in which the arm 108 for the deposit bank will be lowered, it is evident that the rack 67 for the deposit bank will be moved one step toward the left, and likewise it can be seen that when the disk 111 "for the withdrawal bank is positioned so that the arm 108 appropriate thereto is lowered, the withdrawal rack will be moved one step, in order to bring the Total credit and Total debit designations to the printing line.

The means whereby the disks 111 are adjusted by the total lever 123, will now be described.

The disks 111 have fast thereto a segmental member 113, which meshes with teeth 114 of a rack 115 (Fig. 6) slidably mounted on the two right-hand studs 68, above mentioned. At its right-hand end, this rack carries teeth 116 which mesh with teeth formed on a segment 117, fast on a shaft 118. The shaft 118 at its inner end carries a spiral gear 119 (Fig. 2), which inc-shes with the spiral segment 120, to which is secured an arm 121, loose on the rod 61. link 122 pivotally connects the arm 121 with the total lever plate 123, which plate is old and well-known in machines of this type. It can be seen that when the total lever is moved down, the plate 123 will be rotated in a counter-clockwise direction. This will raise the link 122 and rock the arm 121 and spiral segment 120 counter-clockwise. thereby rotating the spiral gear 119, shaft 118 and segment 117 (Fig. 6) in a counterclockwise direction. fl 'his will move the rack 115 toward the left, and through the segment 113, will drive both of the discs 111 in a clockwise direction a sufiicicnt distance to position the discs appropriately to the position of the total lever.

Operation.

If a deposit is to be entered, one of the deposit keys 30 (Fig. 1) is depressed which causes a corresponding totalizer (not shown) to be selected and engaged with the actuators, and appropriate type characters to be set up. At the same time a totalizer corresponding to the zero position of the withdrawal bank and selected under control of the zero stop pawl in such bank, is also engaged with the actuators. The amounts of the deposits are added individually into the totalizer selected under the control of the zero stop pawl of the withdrawal bank, as well as into the totalizer selected under control of the key depressed in the deposit hank. As the type wheels associated with these banks of'keys have blank zero positions, no characters will be printed corresponding to the totalizer selected under control of the zero stop pawl of the withdrawal bank. When the total lever 123 is moved out of its adding position into a position corresponding to the withdrawal bank and the machine is operated without depress ing a key in said bank, the totalizer corresponding to the zero position of the withdrawal bank is selected and engaged and the rack setting mechanism in Fig. 5 is permitted to function to move the rack 67 one step to the left to set up a character indicating that the figures printed represent the total in the deposit totalizer.

Thus in entering a series of deposits and withdrawals, the operator will set up the amount of each item, press the proper transaction key 30 in the deposit or withdrawal bank (Fig. 3) and operate the machine.

The key 30 will select the proper transaction totalizer on the front or back totaliz er depending upon the key selected, but since only a single key 30 is depressed, the zero stop pawl d1 in that row wherein no key is depressed, controls the position of the corresponding differential arm 45, the latch of 70 I which is disconnected in the zero position to automatically select the grand totalizer for that column wherein a key has been depressed. Thus the zero stop pawl associated with the withdrawal bank of keys 30 selects for operation the grand totalizer on which all deposit items are registered, and vice versa. There is a rack bar 67 (Fig. 5) for each row of transaction keys 30, anddepending upon the particular key 30 depressed, the corresponding rack will be adjusted through the differential arm 15 (Fig. 1) beam 55, link 5?, arm 59, worm segment 60, gear 62, shaft 63, and toothed segment 66 (Fig. 5) to cause the rack teeth 69 to turn the appropriate wheel 71 meshing with the pair of type carriers 72, T3 to set the proper type at the printing line. So long as the total lever 123 remains in the add posit-ion, the racks 67 can reciprocate to any extent permitted by the particular key 30 depressed, the projections 90 on the racks passing freely beneath the shouldered cou- 'pling members 92 which are supported in their elevated idle positions by the arms 108, and although the coupling members travel back and forth at each operation of the machine, the supporting faces of the arms 108 are of sufiicient extent to maintain the coupling members idle, so long as the high spots .orlobes of the cam disks 111 remain in the path of the projections 110 on the arms 108.

In the particular embodiment of the invention herein selected for illustration, the various classes of deposit items are registered on their corresponding totalizers arranged on the back totalizer line, and the Various classes of deposit items are registered on their corresponding totalizers on the front totalizcr line, but the totalizer on which is accumulated the grand total of all the deposit items, is arranged on the front totalizer line, in alignment with the withdrawal item totalizers, andvice versa. \Adjustment of the total lever 123 from its normal add position to any of its other positions, operates ,118 mechanism to select one or another of the totalizer lines as desired. 1

Whcn'it is desired to take a total of the deposits, for instance, the operator shifts the total lever 123 from its normal add position, to a position to select the front totalizer line for operation, and as the deposit grand totalizer is at one end of the front totalizer line, it is selected by the zero stop pawl 41 for the withdrawal ank. 1'2

Adjustment ofthe total lever 123 to its lowest position to select the front totalizer line, operates through link 122 (Fig. 2), arm 121, worm segment 120, gear 119, shaft 118, sector 117, and rack 116 (Fig. 6) to shift 13.

the foremost disk, seen in Fig. 5, will pass from beneath the projection 110 on the foremost arm 108, whereupon the foremost spring-actuated coupling member 92 will rock in clockwise direction until its shoulder 91 rests on the bar 67 just in front of the projection 90 on such bar.

At the same time the rearmost cam disk 111 which has three successive lobes formed on its periphery, turns to free its supporting arm 108, whereupon the corresponding coupling member 92 rocks clockwise, but is immediately restored to idle position by the succeeding shorter lobe, so that when the total lever 123 is in its extreme lowest position of adjustment, the rearmost cam disk 111 zero position, against the tension of the spring-actuated restoring dog 104, the sup porting rods 68 and the slots in the bar 67 permitting this one step backward movement of the bar. And the bar 67, through its rack 69, pinion 70 (Figs. 5 and 7) sleeve, and pinion 71, rotates the corresponding upper and lower type wheels 72, 73 one step backwardly past their normal blank positions to locate the proper designating type TD at the printing line,

The rearmost coupling member 92 (not seen) operates similarly but being held in idle position by its arm 108 performs no function.

As the machine completes its operation,

to accumulating another set of deposits and withdrawals.

The effective coupling member 92 when restored to its right-hand position, enables the spring-actuated dog 104 to restore the particular bar 67 actuated one step to the right, to position type wheels 72, 73 with their blank spaces at the printing line.

In the foregoing description, it has been assumed that the bar 67 lies in its home position at the time when the totallever is shifted to its extreme lowest position;

Due to the usual minimum movement mechanism with which machines of this type are equipped, the bars 67 will most probably occupy any of their other positions, ratherthan their home positions.

Read and reset operations on these ma-' chines involve a double operation, as is well known in the art, during the first half of which, the bars 67 are restored to their home positions. 7

Consequently when the selected coupling member 92 is released by its arm 108 and rocks clockwise towards the bar 67 the elongated finger projecting to the right (in Fig. 5) from the shoulder 91 on the coupling member rests upon the projection 90 in whatever position it may be, other than its home position, to prevent the ,shoulder 91 from'dropping behind the projection 90, and as soon as the. bar 67 is restored to its home position in a total taking operation, the projection 90 escapes the finger, and the coupling member 92 snaps its shoulder 91 in front of the projection 90. v

The operation with respect to withdrawals and the totals thereof-is the same as for deosits. e

lVhile the form of mechanism herein shown and described is admirably adaptedto fulfill the objects primarily stated, it is to be understood that it is not intended to confine the.
